Description
Technical field
This utility model relates to a kind of disconnecting switch.
Background technology
Disconnecting switch, i.e. when dividing position, has between contact and meets the insulation distance of regulation requirement and significantly disconnect mark；When closing position, can carry the switchgear of the electric current under normal loop condition and the electric current under abnormal condition (such as short-circuit) at the appointed time.
Disconnecting switch, generally referred to as high voltage isolator, i.e. rated voltage is in 1kV and above disconnecting switch thereof, often referred to simply as disconnecting switch, being to use most a kind of electrical equipment in high-voltage switch electric appliance, the principles and structure of itself is fairly simple, but owing to usage amount is big, functional reliability requires height, and the impact on electric substation, the design of power plant, foundation and safe operation is the biggest.Disconnecting switch be mainly characterized by without arc extinguishing ability, can only divide in the case of there is no load current, close circuit.Disconnecting switch is used for each step voltage, is used as to change circuit and connects or make circuit or equipment and isolated from power, and it does not stop ability, can only operate after first being disconnected by circuit with miscellaneous equipment again.Typically with the interlock of maloperation when preventing from switching on-load, it is sometimes desirable to pin prevents from disconnecting switch under the magneticaction of big fault.General one group of disconnecting switch of two each installations before and after chopper, purpose is all intended to, by chopper and isolated from power, form obvious cut-off point；Because chopper originally uses oil-break, oil-break needs often maintenance, therefore will there be obvious cut-off point two sides, is beneficial to maintenance；Generally, outgoing line cabinet is to be powered downwards by switch cubicle from bus above, one group of disconnecting switch is needed to be intended to and isolated from power before chopper, but sometimes, also the possibility of incoming call is had after chopper, as sent by the counter of other loop, capacitor etc. send by the counter of device, therefore is also required to one group of disconnecting switch after chopper.
Current existing isolator operation is inconvenient, and action stability is relatively low, and usage safety performance is the highest.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of reliable and stable, and service life is long, easy for installation, the disconnecting switch that security performance is high.
For solving the problems referred to above, this utility model adopts the following technical scheme that a kind of disconnecting switch, including frame, rotating shaft, insulator and conducting rod, described rotating shaft is located in frame, described insulator is located in frame, described insulator is fixing with frame to be connected, the first support and the second support it is respectively arranged with on described insulator, it is provided with moving contact on described first support, described moving contact is electrically connected with conducting rod, it is provided with Mume flower contact and conductive plate on described second support, bearing and drive rod are installed in described rotating shaft, described bearing is connected with axis of rotation, described drive rod side is provided with connecting lever, described connecting lever is hinged with conducting rod and drive rod respectively.
As preferably, described conductive plate is electrically connected with Mume flower contact, and Mume flower contact patches reliably, is remarkably improved through-current capability and the dynamic and thermal stability performance of switch.
As preferably, described insulator is that inclination angle is arranged, and keeps easy for installation.
As preferably, described first support and the second support are fixing with insulator respectively to be connected, and keeps Stability Analysis of Structures reliable.
As preferably, described conducting rod is round copper pipe conducting rod, keeps conductive effect good.
The beneficial effects of the utility model are: the drive rod of setting can rotate in rotating shaft, drive connecting lever that conducting rod is moved horizontally, thus the break-make of control circuit, bearing keeps rotational stability high, and conductive plate is convenient to be installed in circuit.
